We investigate the behavior of solutions of the system of the difference equations. ,
, n=0, 1, 2,…, where
and A, B, C and the initial conditions
are positive real numbers. We show that every solution of this system is bounded and eventually constsnt or eventually periodic with period k+m+2.
Keywords
System of Difference Equations, Positive Solution, Periodicity, Boundedness
